Filter by:This study will investigate the safety and tolerability of multiple intravenous infusions of NX210c with two ascending doses as well as NX210c pharmacokinetics (PK), and pharmacodynamics (PD) effects, firstly in healthy elderly subjects, and the recommended dose to be used for Alzheimer's disease patients, in a second step.
The aim of this study is to compare biomechanical walking parameters between patients with symptomatic lumbar spinal stenosis and healthy elderly.
This study investigates the safety and tolerability of drug IkT-148009 in healthy elderly volunteers (55 to 70 years old). It also looks at the movement of IkT-148009 in the body. This first-in-human study is designed in 3 parts. In Part A, healthy participants will take a single, oral dose of IkT-148009 or placebo. Part A participants will be at the study site for approximately 4 days. In Part B, healthy participants will take an oral dose of IkT-148009 once a day for 7 days. Part B participants will be at the study site for approximately 12 days. In Part C, Parkinson's patients will take an oral dose of IkT-148009 once a day for 7 days. Part C participants will be at the study site for approximately 12 days.
The goal is to address the mechanisms that account for alteration of circadian rhythms with age. As the blood of aged individuals can produce this alteration, the investigators propose to use such blood samples to "age" circadian rhythms in cultured cells. The investigators will verify aged blood-dependent alteration of rhythms and then conduct molecular screens to reverse this decline. If the investigators identify specific genes that can restore molecular circadian rhythm in vitro, the investigators will explore these in animal models (Drosophila, mouse).
The objective of the study is to develop prediction equations for calculating Fat-Free Mass FFM, Total Body Water TBW, Extracellular Water ECW, Visceral Adipose Tissue VAT, total Skeletal Muscle Mass SMM and segmental SMM in a group of elderly. The prediction equations are based on linear regression analysis between the gold standard reference methods Air Displacement Plethysmography ADP, Dual-energy X-ray Absorptiometry DXA, Magnet Resonance Imaging MRI, Deuterium dilution method (D2O) and Sodium Bromide dilution method (NaBr) on the one hand and bioelectrical impedance measurements on the other hand. Multi-frequency bioimpedance is measured for all body segments: right arm, left arm, right leg, left leg, trunk, right body side and left body side using the seca mBCA 515 in standing position and the seca mBCA 525 in standing and lying position.
This study is conducted to verify the relationships between yoga efficacy and bioactive materials in the blood of Korean elderly.
To understand the effects of a novel dietary supplement when used in conjunction with a healthy lifestyle exercise program and to define biomarkers that are specific to sarcopenia. A primary aim in the present study is to determine whether a relationship exists between positive changes in body composition through increases in lean mass and reductions in body fat following oral supplementation of naturally occurring food components in combination with exercise. The purpose of the present study is to examine the effects of a multi-nutrient supplement in combination with an endurance and resistance based exercise intervention in a cohort of older adult men with varying degrees of sarcopenia as compared to younger male controls (McMaster/CIHR/Exerkine project). A sub-purpose nested within the study is to provide serum and muscle samples for use in an aging/sarcopenia biomarker discovery study taken at pre-intervention for the young and older men (Buck Institute/Astellas project).
The research objective of this study is to determine whether an intervention and associated robotic device called "Assisted Movement with Enhanced Sensation (AMES) can be used to enhance balance recovery following an unexpected loss of balance by conditioning areas of the brain involved in lower-limb (LL) motor control. It is hypothesized that AMES can improve balance recovery, gait, and reduce falls in near-frail elderly people by improving LL strength, speed, and coordination. AMES, is a medical intervention and robotic device originally developed to aid patients' recovery from injuries to the central nervous system that limit movement. Earlier published studies demonstrated a unique property of AMES, namely that it is capable of reducing sensorimotor impairment in the severely impaired, an underserved population of patients with brain and spinal cord injuries. AMES applies assisted movement, biofeedback, and sensory stimulation simultaneously and non-invasively to the upper or lower limb, the initial intent being to address impairments such as weakness, spasticity, sensory loss, and dyssynergia (i.e., co-contraction). These reductions in impairment are achieved through cortical plasticity. In the present study, the same methodology will be applied to the lower limbs of the near-frail elderly to reduce falls by training faster reaction times, stronger reactions, and more coordinated recoveries from slips and trips
The population is aging worldwide, which requires more attention to health needs and leads to a dramatic increase in health care costs. Prevention or delay of onset of disorders associated with aging is needed. Dietary intake of pectin, a dietary fiber, may have beneficial effects on gut health parameters, i.e. intestinal barrier function, immune function and microbial composition. As intestinal barrier function may be compromised in the elderly we will investigate whether the effects of pectin on selected parameters of gut health differ between young vs. older individuals. The primary objective of this study is to investigate the effects of aging on pectin-induced changes in intestinal permeability. Furthermore, this study has seven secondary objectives. This study conforms to a randomized, double-blind and placebo-controlled design including two parallel arms.The study population consists of Healthy human volunteers (male and female), 18-40 and 65-75 years old, BMI 20-30 kg/m2. One group will receive 7.5 grams of pectin supplements twice daily for four weeks. A second group will receive 7.5 grams of placebo supplements twice daily for four weeks. Before and after the supplementation period, several measurements will take place. The main study parameter is the change in urinary sugar excretion ratio before and after the intervention period.
